Ok I got the ship rendered but it looks rather dull. How do I add colour using blender? :?:

Use materials and textures. The Blender material system is very cool and extremely flexible.
Here's an example of what I've been able to produce in Blender...

This uses a Voronoi texture with yellow layered on top of a base color. I'm at work right now, so I don't have access to get you the actual texture settings I used to do this. If you're interested I can get it for you later...

Sure. :)
Start with your ship body in object mode. I don't know what Blender version you're using, but I'm on 2.63. Below is what my screen looks like right now:

Currently the Materials panel is selected. This is where you can add and remove Materials on your model. Once you've added a material using the plus sign to the right of the Materials list, you can set its base colors and then click Textures to add texturing.
Materials and textures have a huge array of stuff that you can do with them. About the only way you can learn what most of this does is to play with it. I can tell you that Voronoi noise textures are incredibly flexible. Here I'm using two textures layered to produce the effect in the above screenshots.
Layer 1 is a Voronoi texture (size 0.25, nabla 0.025), used entirely to generate the color effects. The mapping subpanel lets you set what values of the material will be affected by this texture (only color is selected here).
Layer 2 is a Stucci noise texture (size 0.1, turbulence 6.0), used for the raised ridges that you see in the texture. This texture maps only to the "normal" attribute of the material.
Which textures you use depends entirely on the effect you want. Again, I can only advise you to play around a lot and see what fits your vision of what you want an object to look like. It's also possible to use Blender's sculpting tools to influence your object's appearance.

I make my spritesheets using ImageMagick. It's a command line tool that's very scripting friendly. If you're on Windows, you can use PowerShell as the scripting engine, which worked out wonderfully for me. The graphics.zip file I've attached has my own current spritesheet and mask, along with the script that I used to generate both based on the set of facings that I rendered from Blender.
The basic steps are:
1. Make a spritesheet.
2. Replace the non-black parts of the spritesheet with pure white.
3. Save.
In ImageMagick, I join all the images together to make the spritesheet and save it as a .png (with alpha turned on). Then I add transparency to all non-black colors over a white background, also saved as a .png with layers. That's the mask. The final step flattens the mask and saves it and the spritesheet as JPG.

Steelwing:
How did you render the facings? Did you individually render them/have your own rotation track/ know how to use one?

What I do is to re-render the ship with a black texture and a white background, then invert the colours of the resulting frames. Then stitch the frames with GIMP.

Individually, via a script. That's what that text panel is: a python script that renders the ship at 40 facings.
As far as "rotation track", no, I have no clue what that is.

I have been such an idiot. I found that I can use the microsoft office to make the bmp mask.

2003 I went to edit pictures, colour ,then I put the saturation and hue down until it was as white as possible then I pressed the enhance colour button and it said click on the picture were it must have white so I clicked on the coloured ship and they all turned white (it may take a bit of fiddling to get it right) I did it with png and bmp sprit sheets rendered with wolfys sprit sheet generator. :D

Cool! Reminds me of the graphics style of Oolite.
